I really, really wanted to like this... I used it for two weeks and reverted to DarqUI's pet window. I did like the additions of the /pet ranged and /pet attack icons.

I wish it were rectangular instead of having stepped sides, so that it would fit neatly against the merc window... the top two icons were so small for me that I could not tell what they were. I figured out one of them, but never did figure out the other. And the window background was always a bright white, no matter what the window settings were.
